Embodiment Construction
[0029] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
[0030] The present embodiment is a blood cell analysis device using the present invention for blood-related examination and analysis. Hereinafter, the blood cell analysis device according to this embodiment will be described with reference to the drawings.
[0031] figure 1 It is an external view of the blood cell analysis device 1 according to this embodiment.
[0032] The blood cell analyzer 1 is a multi-item blood cell analyzer that detects white blood cells, red blood cells, platelets, etc. contained in a blood sample and counts various blood cells. A blood cell analyzer 1 includes a measurement unit 2 , a transport unit 3 arranged in front of the measurement unit 2 , and an information processing unit 4 . Peripheral blood collected from a patient, that is, a blood sample is loaded into the sample container 11 . A plurality of sample containers 1...

The present invention provides a blood cell analysis device, comprising: a sample preparation unit for preparing a first measurement sample in which a first reagent is mixed in a blood sample and a second sample different from the first reagent is mixed in the blood sample. a second measurement sample of the reagent; an optical detection unit for irradiating light to particles contained in the first and second measurement samples respectively flowing through the flow cell, and detecting the particles respectively contained in the first and second measurement samples; The light emitted by the contained particles outputs the first and second detection signals respectively; the control part performs the first classification of white blood cells and counts the first number of white blood cells according to the first detection signal, and performs the second classification of white blood cells according to the second detection signal. Classifying and counting the second number of white blood cells; the output unit, according to the detection result of the particles whose waveform amplitude of the first detection signal is above a certain value, outputs one of the first and second white blood cell numbers and takes it as the blood sample white blood cell count.
Description
technical field [0001] The invention relates to a blood cell analysis device for counting the number of white blood cells in a blood sample. Background technique [0002] Conventionally, there is known a blood cell analyzer that mixes a reagent into a blood sample to prepare a measurement sample, and counts the number of white blood cells in the blood sample from the measurement sample (for example, refer to JP-A-2008-008786). [0003] Depending on the blood sample, when a certain reagent is mixed to prepare a measurement sample, leukocytes may agglutinate in the measurement sample. Once the leukocytes are aggregated in the measurement sample in this way, the leukocytes formed by the aggregation of several leukocytes are counted as one leukocyte, which may affect the measurement accuracy of the leukocyte count. Contents of the invention [0004] The scope of the present invention is defined only by the appended claims and is not limited in any way by the statements in thi...
